If the sump is similar to that of an RB26DETT no it won't just bolt straight on as the RB26DETT sump is a bit wider on the drivers side and has a number of 8mm bolts on this side to compensate for the weight of the front diff, it can be made to fit the RB30 block but there is a bit of work in doing this.

cheers

if you look at the bottom of an rb20 block in a GTS4, it has 2 complete sets of bolt holes for the 2 different sumps. The 4wd sump bolts up to the outer set of holes using 8mm bolts, whereas the 2wd sump bolts up to the inner set of bolts using 6mm bolts. There are also different oil pickups between the 2wd and 4wd models, although this would be easier to fix if you're going from 2wd (rb30) to 4wd, than it was for me to go the other way (i'm using a GTS4 rb20 in a rwd configuration, and it was a complete pain in the arse, despite the assurances of the import wrecker)

Keep the thread going ppls.

Interesting read Belly_up! :D

So what your saying is you could make an adaptor plate that is similiar to that of say a turbo flange adaptor plate.

You would then have to look at extending the oil pick up slightly to accomodate for the height of the adaptor plate.

It would also make lowering the engine slightly difficult??? Due to the 4wd gear.

This would require one to use a RB26 head or a custom plenum on the rb25 head as to prevent bonnet fouling issues.

I would seriously look at a rb26 head.

Has the injectors to make some decent power, slightly better cams, solid followers(higher .050" lift), and it will work perfectly with the RB20DET's wiring loom and ecu(powerfc) providing you wire in the injector resistor pack from a GTR/300ZX.

Any one have pics of the RB20DET GTS4 or GTR sump and block bolt up pattern?

Cubes: That was my next question. We definatly need some photos of the patterns here. Has anyone seen the RIPS adapter plate? And did he use a custom plenum on the 25 head does anyone know?

Really i would love to start work on an RB30DET but have to clear up the issues with the sump mounting and possible clearance issues the adapter plate could cause with the sump fouling on something.

It's for an R32 GTS4 btw.

    • I've owned a few scooters over the years, a Vespa PX oil burner was my first scooter, followed by a few others, including a little 50cc BeeWee that I used as a barracks bike, and I've had a blast on all of them, they really are the cheapest for of city/suburb transport around The only issue with scooters in Australia is lots of people look down on them due to their size,  maybe they need a big bike to make up for something else where they are lacking, unlike Europe and Asia where every man an their dog owns one, and now that filtering is legal in NSW, local traffic is never a issue Not to say I haven't owned my share of big cc bikes over the years, but they were for more blasting through the hills or Hwy riding where it needed to sit on Hwy speeds Safety wise, I ride like everyone is always trying to kill me, everyone is running a red, or running stop/give way signs, or generally asleep at the wheel, which most people are duringtheir commute, I also ride really safe, and give myself, and everyone else enough room in case I need to pull some hasty evasive actions, I've done a few rider training days over the years, which has come in handy on more than a few occasions  As for mods, there's nothing really, and yes your right about aftermarket exhaust, all you get is loud and obnoxious noises from them, like every 250-300 cc you hear with a aftermarket muffler, in saying this I did put a rear muffler from a 125 Aprilla on one of my old 125 scooters, it was horrendous and no amount of full face helmet and ear plugs would dampen that noise As for coming from the Harley, and what a overpriced POS that was, I no longer do big rides as my poor old busted joints ache after about 1/2 an hour of riding, long cruises are so much more enjoyable now in a car, so a big bike would be pointless   
    • Oh wow, it's easy to forget how cheap these can be. Probably the cheapest way to travel. Though people in cars here tend to be morons and I would not feel very safe. Were scooters ever big in Australia? It used to be the thing growing up in Europe ~20 years ago. 50/70/125ccm Peugeot or Yamaha and some others. Utterly obnoxious Polini race exhausts. Kick stands that slant as much as possible. So loud. So much noise for really not moving very fast at all. But it felt cool at the time. Not sure where I'm going with this, but there is an aftermarket for mopeds! Though I'd have pictured you more for a Goldwing kind of guy after growing out of the Harley.
    • You need to know I am sorry for this.  
    • As the MX5 isn't apparently "manly" enough, and I need something for runs to the local shops, and also take to my part time job at the salon, basically I can keep the MX5 away from car parks and stuff......like "flying lockers", I was wondering what I could buy to fix this issue LOL, I pick up a new Yamaha 125 Delight this arvo from Trooper Lu, basically a R1 that you can fit a slab of beer on between your feet, also, it was $29400 cheaper than a R1, so actually it's 2 x better than a R1    
    • Nah. H2S. H2S is "rotten egg gas", which is what is associated with no cat. SO2 is equally nasty, and if you've ever smelt it you'll know all about it. More of a choking, acid in the back of the throat sort of thing. But you can only smell it in a narrow range up to about 1ppm. Above that, it irritates your mucous membranes, but you don't smell it.
